The invention relates to products useful for home laundering, and more particularly to adjustable strength bleaching compositions, highly advantageous packaging of such compositions, and a method of bleaching involving the combination of the two. More specifically, the invention concerns a highly practical and saleable laundry aid which can be used both on sensitive fabrics/dyes as an all-fabric safe oxygen bleach, and on less vulnerable fabrics/dyes as a much more effective hypohalite bleach of potency similar to that of liquid chlorine bleach. The invention is concerned with the use of an alkali metal halide activator with an oxygen bleach which is packaged in a two compartment package to keep the components separate before use.

Adjustable strength laundry bleaching using a two compartment package

A fabric conditioner composition is applied to an air-permeable sheet and variably displaced so that the conditioner occludes interior interstitial spaces in certain regions of the sheet to block air flow therethrough, leaving other regions of the sheet with interstitially open spaces.

Method of producing air-permeable fabric conditioner sheet for laundry

A fabric conditioner composition is distributed on an air permeable sheet in such manner that the conditioner occludes interior interstitial spaces in certain region of the sheet to block airflow therethrough, and other regions of the sheet have interstitially open spaces, there being additional interstitial spaces in those other regions which are relatively smaller and which contain remanent conditioner.

Granular peroxygen bleaching and laundering compositions containing a percarbonate as a source of available oxygen are stabilized by the addition of from 0.1 to 2.0 percent of a particulate siliceous matter such as amorphous silica. To prevent caking and promote flowability of the compositions, from 0.05 to 1.0 percent corn starch, diethyl phthalate or mixtures thereof is included.

Peroxygen bleaching and laundering compositions

Composition for a clear blue colored, stabilized liquid peroxygen bleach, suitable for household laundry use on all fabrics, whose coloring dye is rendered non-substantive to natural or synthetic fibers by the inclusion of a non-ionic surfactant as an anti-dyeing agent having an HLB value within a predetermined range.

Liquid peroxygen bleach

A solid product for rub-on application to stains and soil deposits on fabric preparatory to laundering, comprising blended water soluble non-ionic detergent and stable laundry enzyme uniformly dispersed therein, and the method of manufacturing the product.
